Aalborg Instruments
Design Features
- high precision two-way metering valves in aluminum
- unparalleled precision and resolution in controlling
- operate continuously without overheating; eliminates
A line of electronic two-way metering valves, these high precision linear stepping motors drive the valve spindle. The resolution of the stepping motor driven needles is 0.0005"/step. Low differential pressure valves, may be operated continuously (100% duty cycle).Valves stay in position as when de-energized.
Advantages over solenoid operated valves include cool operations, i.e. there are no control operating problems due to coils heating up, extremely fine resolution, very low differential pressures and high operating pressures. Valves are controllable by TTL compatible logic level and analog 0 to 5 Vdc signals.
